If you're a tinkerer, it's perfectly fine for temp control. TC requires more than a fair bit of dialing-in for new coils/coilsets, though. I own one, and I'm quite happy with mine using 316L stainless in my DogeV2S in TC mode. That said, if you DO NOT like having to go through dialing in a new coil with trial and error, you'll probably find the XCube II rather frustrating in TC mode. Watt mode is lovely, period.
